My cabin consists of two rooms. The smaller back room is my bedroom. The larger room in front of it serves all other purposes, being dining room, kitchen, and living room combined. From my bunk, I cannot see directly into the front room. A flimsy partition separates the bedroom from the living room. It consists of rough-hewn boards that in the process of shrinking have left wide cracks in the wall, and in addition to this the door between the two rooms is seldom closed; so that while I could not see into the adjoining room, I could hear anything that might go on within it.

I do not know that I am more susceptible to suggestion than the average man; but the fact remains that murder, mystery, and gangster stories always seem more vivid when I read them alone in the stilly watches of the night.

I had just reached the point in the story where an assassin was creeping upon the victim of kidnappers when I heard the front door of my cabin open and close and, distinctly, the clank of metal upon metal.

Now, insofar as I knew, there was no one other than myself camped upon the headwaters of the Little Colorado; and certainly no one who had the right to enter my cabin without knocking.

I sat up in my bunk and reached under my pillow for the .45 Colt automatic that I keep there.

The oil lamp faintly illuminated my bedroom, but its main strength was concentrated upon me. The outer room was in darkness, as I could see by leaning from my bunk and peering through the doorway.

"Who's there?" I demanded, releasing the safety catch on my automatic and sliding my feet out of bed to the floor. Then, without waiting for a reply, I blew out the lamp.

A low laugh came from the adjoining room. "It is a good thing your wall is full of cracks," said a deep voice, "or otherwise I might have stumbled into trouble. That is a mean-looking gun I saw before you blew out your lamp."

The voice was familiar, but I could not definitely place it. "Who are you?" I demanded.

"Light your lamp and I'll come in," replied my nocturnal visitor. "If you're nervous, you can keep your gun on the doorway, but please don't squeeze the trigger until you have had a chance to recognize me."

"Damn!" I exclaimed under my breath, as I started to relight the lamp.

"Chimney still hot?" inquired the deep voice from the outer room.

"Plenty hot," I replied, as I succeeded at last in igniting the wick and replacing the hot chimney. "Come in."

I remained seated on the edge of the bunk, but I kept the doorway covered with my gun. I heard again the clanking of metal upon metal, and then a man stepped into the light of my feeble lamp and halted in the doorway. He was a tall man apparently between twenty-five and thirty with grey eyes and black hair. He was naked but for leather trappings that supported weapons of unearthly design—a short sword, a long sword, a dagger, and a pistol; but my eyes did not need to inventory all these details before I recognized him. The instant that I saw him, I tossed my gun aside and sprang to my feet.
